Maybe the answer is

<h3>Explanation</h3>

The L between 2 and 3 shows that yeah... it has a neat degree (sorry dont know how to explain lol) and so the triangle which has 3 side and total 180° will be 180° : 3 = 60 because the degree is neat. :v

Need help with this problem, it's got me stuck PLZ

faust18 [17]

24x^2 +25x - 47 53

----------------------- = -8x -3 - ---------------

ax-2 ax-2

add 53/ax-2 to each side

24x^2 +25x - 47+53

----------------------- = -8x -3

ax-2

24x^2 +25x +6

----------------------- = -8x -3

ax-2

multiply each side by ax-2

24x^2 +25x +6 = (ax-2) (-8x-3)

multiply out the right hand side

24x^2 +25x +6 = -8ax^2 +16x-3ax +6

24 = -8a 25 = 16 -3a

a = -3 9 = -3a

a = -3

Choice B

Complete the square to make a perfect square trinomial. Then, write the result as a binomial squared. q2+11q

Sedbober [7]

Answer:

$(q+\frac{11}{2})^2-\frac{121}{4}$

Step-by-step explanation:

We have been given an expression $q^2+11q$ . We are asked to complete the square to make a perfect square trinomial. Then, write the result as a binomial squared.

We know that a perfect square trinomial is in form $a^2+2ab+b^2$ .

To convert our given expression into perfect square trinomial, we need to add and subtract $(\frac{b}{2})^2$ from our given expression.

We can see that value of b is 11, so we need to add and subtract $(\frac{11}{2})^2$ to our expression as:

$q^2+11q+(\frac{11}{2})^2-(\frac{11}{2})^2$

Upon comparing our expression with $(a+b)^2=a^2+2ab+b^2$ , we can see that $a=q$ , $2ab=11q$ and $b=\frac{11}{2}$ .

Upon simplifying our expression, we will get:

$(q+\frac{11}{2})^2-\frac{11^2}{2^2}$

$(q+\frac{11}{2})^2-\frac{121}{4}$

Therefore, our perfect square would be $(q+\frac{11}{2})^2-\frac{121}{4}$ .

which of the following graphs shows a negative linear relationship with a correlation coefficient, r, close to -0.5.

Harrizon [31]

Answer:

In the graph attached there is a sample generated with a correlation coefficient r=-0.5.

Step-by-step explanation:

A value of r that is -0.5 shows that there is a certain correlation and that this correlation is negative.

As there are no examples in this question, I searched for a generator of random samples with a user-input correlation coefficient between the two variables.

In the graph attached there is a sample generated with a correlation coefficient r=-0.5.
